Understanding Rock-Salt Structure
The rock-salt structure is a common arrangement found in ionic compounds, particularly in compounds such as sodium chloride (NaCl). This structure is characterized by specific coordination numbers for cations and anions.
Coordination Numbers
- In the rock-salt structure, each cation is surrounded by six anions, and each anion is surrounded by six cations.
- Therefore, the coordination number of both the cation and the anion is six.
Analysis of the Provided Options
- Option A: Coordination number of cation is four whereas that of anion is six.
- Incorrect: As established, both cations and anions in the rock-salt structure have a coordination number of six.
- Option B: Coordination number of cation is six whereas that of anion is four.
- Incorrect: The coordination number for anions is also six, not four.
- Option C: Coordination number of each cation and anion is four.
- Incorrect: The correct coordination number is six for both species.
- Option D: Coordination number of each cation and anion is six.
- Correct: This statement accurately describes the rock-salt structure.
Conclusion
Based on the analysis, the incorrect statements are A, B, and C. The correct understanding of the rock-salt structure is crucial for grasping the properties and behaviors of ionic compounds in solid-state chemistry.

Can you explain the answer of this question below:On the basis of aromaticity, there are three types of compounds i.e. aromatic, non-aromatic and antiaromatic.The increasing order of stability of these compounds are is under:Anti-aromatic compound non-aromatic compound aromatic compounds. Compounds to be aromaticfollow the following conditions (according to valence bond theory)(i) The compounds must be be cyclic in structure having (4n + 2) e, where n = Hckels number = 0, 1,2, 3 et.c(ii) The each atoms of the cyclic structure must have unhybridised p-orbital i.e. the atoms of thecompounds have unhybridised p-orbital i.e. usually have sp2 hybrid or planar.(iii) There must be a ring current of electrons in the ring or cyclic structure i.e. cyclic structure mustundergo resonance .Compounds to be anti-aromatic, it must have 4ne where n = 1, 2 and it must be planar and undergoresonance. Non-aromatic compounds the name itself spells that compounds must be non-planarirrespective of number of electrons. Either it has 4ne or (4n + 2) electrons it does not matter.The rate of reaction of any aromatic compounds depends upon the following factors:(i) Electron density(ii) stability of carbocation producedHigher the amount of electron density of the ring, higher will be its rate towards aromatic electrophilicsubstitution and vice-versa. Similarly, higher will be the stability of the produced carbocation after theattack of electrophile, higher will be its rate towards aromatic electrophilic substitution. There is a greateffect of kinetic labelling on the rate of aromatic electrophilic substitution. As we known that higher theatomic weight or, molecualr weight, higher will be the van der Waals force of attraction or, bond energy.Since there will be effect of kienetic labelling if the 2nd step of the reaction will be the slow step, (r.d.s.)otherwise there will be no effect of kinetic labelling.Q. Which of the following is correct order of the rate of reaction of C6H6, C6D6 and C6T6 towardsnitrations?A:C6H6 C6D6 C6T6B:C6H6 = C6D6 = C6T6C:C6H6 C6D6 = C6T6D:C6T6 C6D6 C6H6The answer is b.

On the basis of aromaticity, there are three types of compounds i.e. aromatic, non-aromatic and antiaromatic. The increasing order of stability of these compounds are is under: Anti-aromatic compound < non-aromatic compound < aromatic compounds.

Non-aromatic compounds the name itself spells that compounds must be non-planarirrespective of number of π electrons.
